#include <stdio.h>
#define MAX_SIZE 100 //Maximum size of the array

int main()
{
    int arr[MAX_SIZE];
    int i, num, evennum, oddnum;

    // Reads size and elements in array
    printf("Enter size of the array: ");
    scanf("%d", &num);
    printf("Enter %d elements in array: ", num);
    for(i=0; i<num; i++)
    {
        scanf("%d", &arr[i]);
    }

    evennum = 0; // Assuming 0 even numbers
    oddnum  = 0; // Assuming 0 odd numbers

    for(i=0; i<num; i++)
    {
        /* If the current element of array is evennumber then increment evennumber count */
        if(arr[i]%2 == 0)
        {
            evennum++;
        }
        else
        {
            oddnum++; // increment oddnumber count
        }
    }

    printf("Total even  numbers: %d\n", evennum);
    printf("Total odd numbers: %d\n", oddnum);

    return 0;
}

Result:

Enter size of the array: 5

Enter 5 elements in array: 1
